For just the second time ever , astronomers have discovered multiple " Tatooine worlds , " or exoplanets orbiting a pair of sensation , in the same star system . The uncovering is further validation that these Star Wars - like planets are more mutual than scientist previously mean .
Tatooine worlds , or circumbinary planet , areexoplanetsthat exist in star systems with two stars , also known as binary star system . As a result , an beholder standing on one of these planets ' surfaces would see two suns in the sky and experience a pair of sunsets , just like Luke Skywalker on the fictional major planet of Tatooine .

The first circumbinary planet , known as Kepler-16b , wasdiscovered in 2011 . This was closely followed by thediscovery of two more example , Kepler-34b and Kepler-35b , in 2012 .. Since then , a sum of 14 unlike circumbinary world have been discovered . ( NASA ’s Kepler space scope , which was decommissioned in 2018 , was used to detect a majority of these Tatooine worlds . )
In a novel study , published June 12 in the journalNature Astronomy , stargazer focused their globe - ground scope on BEBOP-1 , a star system around 1,320 lite - years from our planet . The squad was attempting to study BEBOP-1b , a circumbinary major planet first discovered in 2020 . But rather , they detected a new circumbinary major planet BEBOP-1c — the 15th known Tatooine world . This also make BEBOP-1 a multi - planetary circumbinary system ( MCS ) . ( The name BEBOP get along from the " Binaries Escorted By Orbiting Planets " project , which find the wizard system . )

The researchers ' data suggest that the newly discovered BEBOP-1c is around 65 time more monolithic than Earth , or around five time less monolithic than Jupiter , investigator spell in astatement . The antecedently known BEBOP-1b is around the same sizing as Saturn .
BEBOP-1 is the secondly known MCS . The first , Kepler-47 , wasdiscovered in 2012and has three exoplanets .
In the past tense circumbinary planets were assumed to be extremely raredue to the gravitational complexness of their potential scope . But the recent spate of discoveries of these globe shows it is not only possible , but amazingly usual . render that , up to half of the stars the size of our sun in theMilky Wayform in pair , there could be one thousand of these public in our galaxy waiting to be observe . Past evidence has even suggested that our own sunwas possibly part of a binary systembefore the solar system was formed .
— Strange star system may hold first grounds of an ultra - rare ' dark matter star '
— There may be hundreds of millions of inhabitable satellite in the Milky Way , Modern study suggests
— ' unimaginable ' new ring system discovered at the edge of the solar system , and scientists are queer
In 2021 , researchers also get word the first " circumtriple planet"orbiting 3 Sunday in a exclusive system , known as GW Orionis .
The team will continue to contemplate the BEBOP-1 system of rules to learn more about how circumbinary planets form . There is also the chance that the BEBOP-1 organisation carry even more planets waiting to be notice . The research worker go for to be able to practice the state - of - the - artJames Webb Space Telescopeto peer more closely at this system in the future to recover out .
